PEDESTAL BASE OPERATING TABLE Filed June 17, 1930 4 Sheets-Sheet 4Patented Feb. 13, 1934 'UNITED STATES PATENT OFFICE PEDESTAL BASEOPERATING TABLE Sylvania Application June 17, 1930. Serial No. 461,667

13 Claims.

My invention relates to an improvement in a pedestal base operatingtable and its novelty consists in the adaptation and arrangement ofparts as will be more fully hereinafter pointed out.

There are many operating tables on the market and a number of pedestalbase operating tables but all of these require the nurse or operatorassisting the surgeon to move from one part of the table to the other inorder to throw the table top to the different necessary positionsrequired during the operation.

This interferes seriously with the efliciency of the person assistingthe surgeon as it takes them away from the head of the patient where itis essential they should be throughout the operation in order to knowthe exact condition of the patient throughout the operation.

My invention solves this serious and difficult problem which has formany years handicapped the quick and easy changes of position requiredto be made in the operating table top at diiferent times during theoperation.

Furthermore, my device has simplified and speeded up the shifting of theoperating table top from one position to another so that the efficiencyof the table has been improved in a very substantial manner therebyeliminating all delays between the necessary shifts of the table topwhich must be made quickly and easily during the different stages of theoperation.

In the drawings 17 is a pedestal base having legs 18 on which aremounted casters 19 in the usual well known manner. A supporting piston20 of usual construction is mounted in the base 17 in the usual wellknown manner and is operated by foot pedal 21 to raise and lower thesame in an oil plunger construction which has been used in this art fora number of years and is the usual construction. On the head of thepiston 20 is rigidly secured a yoke 22 through which is mounted near itshead a shaft 23 and on the shaft 23 are mounted two frames 24 whichpivot thereon by means of bearings 25 of the frames 24. Said frames 24also have a semi-circular segmental gears 26 which are made integraltherewith and which have gear teeth 27.

A bracket member 28 is rigidly secured to yoke 22 and at its outer end ashaft 29 is mounted therethrough so as to rotate freely therein andcarries a hand wheel 30 mounted thereon at its outer end and pinnedthereto in the usual manner. A cut gear 31 is also mounted on said shaft29 inside of said wheel 30 and is pimied to said shaft so as to rotatetherewith and meshes with a worm gear 32 which is cut on the lower endof a driving shaft 33 which is supported in a box 34 mounted over saidshaft 29 thereby enclosing the gear 31 and the gear 32. The upper end ofthe driving shaft 33 is supported in a box 35 which is rigidly securedto the side of the yoke 22 and a worm gear 36 is cut on the upper end ofsaid driving shaft 33'and meshes with the teeth 2'7 of segmental gear26.

A pair of pyramidal supporting members 37 are rigidly secured to theupper side of the frame 24 and table top section 38 is pivotally andhingedly mounted near one end of the same on supporting members 37 onpivot rod 39 in the usual well known manner. A second top member 40containing a kidney bridge (Fig. 2) is pivotally supported on thebrackets 41 mounted in the usual Well known manner at the head of rackbar 42 and is pivotally and hingedly mounted at one end of the same onsupporting members 37 on pivot rod 39 in the usual well known manner.The opposite end of table top 38 is also supported in the usual wellknown manner on brackets 43 mounted on the head of rack bar 44 in. theusual well known manner. Table top head member 45 is pivoted at 46 inthe well known manner and may be dropped .and raised by the usual handoperation or secured in the desired position. Foot section 47 of thetable top is pivoted at one end on the bar 48 in the usual well knownmanner and is supported by the bracket 49 pivoted at 50 on the arm 51which is pivotally secured at 52 to pinion 53 which is internallythreaded to travel over the worm gear 54 on shaft 55.

In the frame 24 is mounted a shaft 59 on the outer end of which ismounted a wheel handle 60 and which is adapted to move along said shaftand is held against being pulled off the end of the shaft by means ofcross pin 61 running through said shaft 59, which also serves as a keyto engage in pocket so as to lock the handle 60 and shaft 59 together sothat they will turn together in that position. A cut gear 62 is rigidlysecured to the inner end of said handle 60 so as to turn therewith. Aspring operated nipple member 63 is mounted in said handle member 60 andis adapted to engage groove 64 in said shaft 59 so as to determine theposition of the gear 62 as clearly shown in Figure 3, but is readilydislodged therefrom as the shaft 59 is pushed inwardly or pulledoutwardly. On the shaft 59 is mounted a spiral gear 67 in such a waythat it will rotate with said shaft 59 and said gear meshes with gear 66mounted on the end of shaft 55 so that the motion of the shaft 59 istransmitted through said gears 67 and 66 to the shaft 55 and the shaft55 has Worm gear 54 and the other parts as already described. A shaft 68is also mounted in the frame 24 on the usual bearings 73 through gearcasing 69 and apair of gears 70 and 80 which are formed together androtate together are rigidly mounted inside of the frame 24 on one end ofthe shaft 68. Another shaft 71 is mounted in the frame 24 on the usualbearings 72 and a cut gear 74 is rigidly secured thereto at the endinside of the frame 24 and the chain sprocket Wheel 75 is also rigidlysecured thereon so as to rotate therewith. At the further end of theframe 24 from the handle 60 and operating part described is anothershaft 76 mounted in bearings 77 and a sprocket wheel 78 is rigidlysecured thereto so as to rotate therewith and a chain 79 travels overthe sprocket wheels 78 and 75 so that said sprocket Wheels and theshafts 76 and 71 to which they are respectively rigidly secured rotatetherewith.

The meshing of the gear 62 with gear 70 insures the rotation of theshaft 68 in either direction as desired, this is illustrated in Figure3. Meshing of gear 62 with gears 80 and 74 effects the rotation of bothshaft 68 and shaft 71 simultaneously by the turning of handle 60, whichis shown in Figure 5. In order to operate the shaft 59 the handle 60 ispulled out so as to engage the key 61 in the pocket 65 whereby the shaft59 will be turned with the rotation of the handle 60 and spiral gear 57will rotate the gear 66 whereby the shaft 55 will be turned.

It is to be noted at this point that the shafts 59, 68 and 71 and also76 extend across the table and engage in a second frame 24 carried onthe opposite side of the table in similar bearings and a second spiralgear 67 meshing with a second gear 66 drives a second shaft 55 with theduplicated elements as described herein and a second set of gear boxes69 and 81 encase a second set of gears 82 and 83 on the shafts 68 and 76operating a second pair of rack bars 42 and 44 in the usual well knownmanner and connected at the upper ends with the table top sections 40and 38 respectively by means of a second pair of supporting brackets 43and 41 respectively.

Kidney bridge 56 is rigidly supported on side frame members 84 beingsecured thereto in a fixed manner. The bridge 56 is composed of a crossbar 85 having a worin gear 86 on one half and a second worm gear 87 onthe other half. A second cross bar 88 having a worm gear 89 on one halfand worm .gear 90 on the other half carries the frame members 91 and thebridge 56 mounted in said frame members 91. Internally threaded pinion92 is mounted over the worm gear 87 of the bar 85 and a similar pinion93 is mounted over the Worm gear 86. Link 94 is pivotally connected at95 to pinion 92 and pivotally connected at 96 to frame 91. A similarlink 97 is pivotally connected at 98 to pinion 93 and pivotallyconnected at 99 to the other frame member 91 whereby the rotation of theshaft 85 in one direction will draw the pinions 92 and 93 outwardlythereon thereby pushing up on the links 94 and 97 and thereby raisingthe frame members 91 and the kidney bridge top 56 as desired. Theopposite 105 rotation of the shaft 85 by means of the crank engaging thekey way at 100 will have the opposite result. The shaft 88 also has akey Way 101 adapted to be engaged by a crank to rotate said shaft ineither direction whereby pinions 102 and 110 103 mounted on the wormgears 89 and 90 and carrying body bracket members 104 may be moved tothe desired positions on the shaft 88, said pinions 102 and 103 beingheld against rotation by the contact of cross bar 165 secured to the 115frame members 91 and which rests against the upper side of the same.

In order to obtain the twelve different principal operating positionscommonly used, the following operations of the table are necessary.

The straight general operating position is shown in Figure 1 and thetilting of the entire table top and frames 24 with their connections asdescribed is controlled by the operation of the large handle 30operating through the gears as described, on shaft 33, whereby thesemi-circular gear 27 is turned to the desired position carrying with itthe frames 24 and the top mounted thereon on pyramidal brackets 37supported on the frames 24 and the operation of the hand wheel 60 and13g gear 62 through the various gears, chains, shafts, pinons and rackbars, as already described operates the different sections 38, 40, 47and 45 of the table top.

In order to secure the reilex abdominal operating position as shown inFigure 8, it is necessary to mesh the gears 62 with 88 and 74 and thenturn the hand wheel 60 to the right whereby the shaft 68 and 71 will berotated to the desired position together with shaft 76 through chain 79over brackets 75 and 78 and through the turning of gears 82 and 83 theoperation of the two sets of rack bars 42 and 44 will be operated.

In order to obtain the Trendelenburg position as shown in Figure 9, itis first necessary to operate the large hand wheel 30 to turn the entiretable top to the desired position, then mesh the gears as shown inFigure 4 and turn the handle 60 to the right.

In order to obtain the reflex thigh position as shown in Figure 16, itis necessary to turn the entire table top to the Trendelenburg positionand then by meshing the gears as shown in Figure 3 and turning the handWheel to the right as far as possible, then unrneshing the gears asshown in Figure 4 and engaging the key 61 in the hand Wheel 6U, turn thehand Wheel 60 to the right thereby rotating the shaft 59 and theconnecting gears and shafts as described.

rEhe Mayo kidney position as shown in Figure 10 is obtained by meshingthe ge-ars as shown in Figure 5 and then turning the hand Wheel 60 tothe left.

The reverse Trendelenburg position, as shown in Figure 6 is obtained byturning the large hand Wheel 30 to the left to tilt the entire tabletop, then attach the Hartley foot rest in the usual Well known positionfor use.

The goitre position as shown in Figure 7 is obtained by first placingthe table top in the Trendelenburg position as already described andthen turning the head rest 45 in the manner as already described to thedesired position.

The pelvic and plastic position as shown in Figure 11 is obtained byreturning the table top to the horizontal position as shown in Figure 1and then unmeshing, the gears as shown in Figure 4 and turning the handwheel 60 to the right.

The cystoscopic position as shown in Figure 12 is secured by meshing thegears as shown in Figure 5 and turning the hand Wheel 60 to the right,then meshing the gears as shown in Figure 4 and turn the hand Wheel tothe right.

The chair position as shown in Figure 13 is obtained by starting withthe table in the horizontal position as shown in Figure 1, then meshingthe gears as shown in Figure 3 and turn the hand Wheel 60 to the right,and then meshing the gears as shown in Figure 4 and turn the hand wheel60 to the right.

The extreme lordosis position as shown in Figure 14 is obtained by rstturning the table top to the Trendelenburg position as already describedand the meshing the gears as shown in Figure 5 and turning the handWheel 60 to the right, then meshing the gears as Shown in Figure 4 andturn the hand Wheel 60 to the right.

The resuscitation position as shown in Figure 15 is obtained by rstplacing the table top in the horizontal position as shown in Figure land then meshing the gears as shown in Figure 3 and turning the handwheel 60 to the left.
